Macklemore secretly welcomes second child with wife Tricia Davis

The American singer, 34, and his wife,Tricia Davis, secretly welcomed their newborn daughter in mid-March, but he only revealed her arrival in a recent interview with Irish radio station Spin 1038.

"I spent it in the hospital, with my brand new daughter who was born right before St Patrick's Day," Macklemore, 34, told hosts Nathan O'Reilly and Nick Karkazis of how he spent the Irish holiday.

Macklemore -- whose real name is Ben Haggerty --is already dad to two-year-old Sloane Ava Simone, who he's so smitten with that he got her name tattooed on his chest.

It's no secret the Thrift Shop singer is very private when it comes to his personal life -- one month on and he has yet to reveal the name of his second baby.

Similarly, he didn't announce that he and Davis had tied the knot until three months after their June 2015 ceremony. Likewise, he kept Sloane's birth that same year a secret until she was three months old.

"We had our beautiful baby girl [Sloane] on May 29th... Got married on June 27th," he announced on Instagram at the time. "Thank you all for being patient, this year has been incredible so far, we love you."

"There is nothing like the joy and happiness that comes from bringing a baby into this universe," he added. "[Sloane] has filled my heart in ways that I never knew were possible."
